BACKGROUND

[0002] 1. Field of the Invention

[0003] This Invention relates to as comfort Air-conditioning,specifically to an air-condition apparatus to provide an air-conditionedenclosure for indoor or outdoor use that is compact and portable.

[0004] 2. Description of Prior Art

[0005] Air-conditioning of space with units employing refrigerants areused for cooling space for personal comfort. Commercial air-conditionershave the following disadvantages:

[0006] (a) Higher Capital investment in the space to be air-conditioned:For effective and efficient use of Air-conditioning requires a room or abuilding to be built with thermal insulation, air infiltration seals,shaded windows and other special requirements. Such special requirementsresult in higher capital investment in addition to the cost of theair-conditioner.

[0007] (b) Higher Capital investment for larger air-condition unit: Theminimum space that could be effectively air-conditioned using thetraditional air-condition unit is an entire room, even if conditioningis required only for a portion of the room that is occupied. Commercialportable air-conditioners have the same limitation. The larger the spaceto be air-conditioned the larger is the air-condition unit required.Larger the unit higher the cost. For example in a bedroom, the minimumspace that requires air-conditioning is the compact space surroundingthe body of the occupants. In current application, the entire bedroomneeds to be air-conditioned. This will result in unnecessary extra costof larger equipment and installation.

[0008] (c) Higher Operation cost: As discussed in previous paragraphstraditional units would be of larger capacity than the minimum neededfor specific applications. Larger the unit higher is the operating costfor electric energy. Cooling of a selective smaller space offers comfortat a lower operational cost. A selected enclosure could be cooled withcommercially available portable air-conditioner however the disadvantageis the portable air-conditioner can not supply cooled fresh air but onlyre-circulates the space air.

[0009] (d) Enclosures available for clean air requirements such asMichael H. Pelosi, III et al U.S. Pat. No. 5,314,377 is not suitable forcomfort Air-conditioning of a compact space, as it requires anindependent source of conditioned air in the place of the clean airsource. In addition, the prior art enclosure has cumbersome structurerequiring complex assembly. The objective of that enclosure is toprovide clean air and not comfort conditioning, so major modification isnecessary before it can be used for comfort air-condition application.

[0010] Commercially available portable air-conditioner can cool anenclosed space however the disadvantage is it cannot supply cooled freshair but can only re-circulates the space air. Thus, none of the currentapparatuses is suitable for providing an air-conditioned enclosure

[0011] Air-conditioned Mosquito net of patents such as San Jianhua et alChina. Pat. No. CN2259099 and Tan Mingsen et al China. Pat. No.CN1163735 illustrates mosquito nets connected to a conditioned airsource by an air duct. Both of these prior art requires an externalsource of conditioned air. In addition, in both of these prior arts,outside air is conditioned and supplied to the enclosure and all of theair is exhausted outside the enclosure. ‘Heat Insulating Mosquito-Net’of He Baoan et al China. Pat. No. CN1061140 illustrates a mosquito netwith plurality of inflatable air-pocket walls. This art has thedisadvantage of requiring inflation of wall air pockets and increasesthe chance of failure of thermal insulation due to puncturing of the airpockets. cl SUMMARY

[0079] Various types of air-condition may be generally referred to butthe invention is particularly adapted to a process of heating orcooling, humidification or dehumidification and filtering of air only.

[0080] The invention comprising of an Enclosure and an air-conditionunit can be fitted on to any flat surface. In the embodiment described,the frame of the Enclosure is structurally fitted onto the floor surfaceand the wall sheets tucked at the floor level under the structure thatforms the floor. This forms a good airtight Enclosure, which isthermally isolated.

[0081] The one sidewall of the Enclosure has two openings with elasticrims to accommodate air ducts i.e. exit air duct and supply air duct ofthe Air-conditioning Unit.

[0082] The Air-conditioning Unit has the traditional parts such ascompressor, evaporator coil, condenser coil, air filter, fans, motor,controls and others assembled as described in the preferred embodimentto supply fresh air and re-circulated cool air to the said Enclosure ofthe preferred embodiment.

[0083] The present invention provides a portable airtight Enclosuresystem with openings for receiving the Air-conditioning ducts and anAir-conditioning Unit for providing a suitable clean, cool andconditioned atmosphere, within the said Enclosure system. The Enclosuresystem can assume various shapes suitably in accordance with the shapeof the frame, which is the structural support for the said Enclosure.

[0087] As an extension of scope of invention, a typical example is tohave a single pre-fabricated foldable enclosure—comprising of frameworkincluding the roof, the sidewall sheets and spacer strips. This issimple to avoid the assembly work involved in the preferred embodimentherein above described in the previous paragraphs.

[0088] The Enclosure is pre-fabricated with the wall sheets and spacerstrips including a roof portion and drapes over the frame structure. Oneside of the wall may be provided with re-sealable opening for peoplepassage preferably with hook and loop fasteners.

[0089] Working of the Invention

[0090] The working of the invention is herein described in detail. Thesaid Enclosure assembly 1, creates an isolated air space above anoccupied surface, an example of such an application is around a bed asshown in FIG. 1.

[0091] The Enclosure isolates the inside space from the outsidethermally and avoids outside air infiltration. The said air opening rims15 and 16, wrap around the said Air Ducts, and offers air passage orconnection with the Air-condition Unit 17. The Enclosure assembly isstructured to be lightweight, to cost less, and to offer quick and easyassembly and disassembly; thus offering portability.

[0092] Enclosure air is drawn through the Exit Air opening 13 and ExitAir Duct 20. Part of the air from Exit Air Duct 20 and Fresh air fromFresh Air Chamber 36 is mixed in the Air Plenum 23. The air is filteredthrough the Air Filter 25 and is moved by fan 24 through the EvaporatorCoil Assembly 26, where it is conditioned. The conditioned air entersthe Enclosure through the Supply Air Duct 21.

[0093] Part of the Exit air from duct 20 passes through the HeatTransfer Duct 37 to Compressor Chamber 31. The Air Damper 39 controlsthe flow of air inside the Heat Transfer Duct 37. Air Damper 39 isadjusted by the Control Knob 38 interconnected by Control Rods and links40. The air in duct 37, pre-conditions, pre-cools or pre-heats the freshair in the Fresh Air Chamber 36. This pre-conditioning of the fresh airby the exhaust air conserves energy. The Fresh Air chamber is suppliedby fresh air through the Air Grills 33 located at the bottom.

[0094] Outside air is also drawn inside the compressor chamber 31,through the air grills at the lower portion of the said Chamber. Airfrom the Heat Transfer Duct 37, enters the said chamber 31, mixes withair in the chamber, and is moved by the blower 27. The blower moves theair mixture across the condenser coil assembly 30, and exhausts itthrough the exhaust duct 28. The exhaust duct's free end may be locatedto exhaust hot air outside of the building through a window or doorwayif the invention is used indoor. For outdoor use the exhaust duct canexhaust to the space.

[0095] Conclusions Ramifications and Scope

[0096] The above description illustrates the Self-containedAir-Conditioned Enclosure provides air-conditioned comfort with freshair at economical capital cost, conserves energy, operates with lowercost, is portable can be assembled easily and has longer life.

[0097] While the above contains many specifications these should not heconstrued as limitations on the scope of the scope of the invention, butrater as an exemplification of one preferred embodiment thereof. Manyother variations are possible a few examples follow.

[0098] The rigid Enclosure Roof of the enclosure can replaced with anassembly similar to the sidewalls, with Wall Sheets and Spacer Strips.The Enclosure Frame structure instead of located outside the enclosurecould be placed inside and support the enclosure. The Enclosure can becolored and have other shapes such as circular, square or combinationthereof. The Enclosure sidewall can have slit opening for entry or exitto the Enclosure that can be sealed and fastened by hook-and-loopfasteners etc.

[0099] The components of the Air-condition Unit can be rearranged toserve the same purpose as this invention. The Air moving devises can beconnected with a longer shaft driven by a single electric motor. Theair-conditioner or its control can be modified to work as a heat pump.The Unit size can be compacted by eliminating the Fresh Air Chamber andHeat transfer duct at the expense of energy conservation.

[0100] Thus the scope of the invention should be determined by theappended claims and their legal equivalents, rather than by the examplesgiven.
